Abstract: Aspects described herein relate to configuring a primary component carrier (PCC) and at least one secondary component carrier (SCC) for transmitting uplink communications to one or more nodes of a wireless network using carrier aggregation (CA) in a first subscription of the UE, and transmitting, to at least one of the one or more nodes, a manipulated power headroom report for the at least one SCC based on a migration from an idle state to an active state in a second subscription of the UE.

Abstract: Embodiments described herein relate to managing communications for a first subscription and a second subscription of a wireless communication device, including, but not limited to, using a reduced re-order release timer having a reduced length in response to determining that a length of a tune-away interval exceeds a threshold. In some embodiments, a reduced status prohibit timer is initiated in response to determining that the length of the tune-away interval exceeds a threshold. In some embodiments, two or more status reports are transmitted during a same status prohibit timer in response to determining that transmission window occupancy exceeds a threshold.

Abstract: A method and apparatus for reducing call drop rate by validating reconfiguration messages based on service data unit (SDU) lifetime are described. A receiving device, such as a user equipment, may determine a receiving delay between receiving a first protocol data unit (PDU) and receiving a last PDU of a reconfiguration message SDU. The receiving delay may be compared with an SDU lifetime. The reconfiguration message SDU may be validated based on the comparison of the receiving delay with the SDU lifetime. A receiving delay that is greater than the SDU lifetime may indicate that the SDU is stale and, therefore, invalid. A receiving delay that is less than the SDU lifetime may indicate that the timing of the SDU is valid and the reconfiguration message SDU is to be processed. An activation time of the reconfiguration message SDU may also be honored or disregarded based on the receiving delay.

Abstract translation: 描述了通过基于服务数据单元（SDU）寿命验证重新配置消息来减少呼叫丢弃率的方法和装置。 诸如用户设备的接收设备可以确定在接收第一协议数据单元（PDU）和接收重新配置消息SDU的最后PDU之间的接收延迟。 可以将接收延迟与SDU寿命进行比较。 可以基于接收延迟与SDU寿命的比较来验证重新配置消息SDU。 大于SDU寿命的接收延迟可能表示SDU过时，因此无效。 小于SDU寿命的接收延迟可以指示SDU的定时有效并且重新配置消息SDU将被处理。 基于接收延迟，重新配置消息SDU的激活时间也可以被兑现或忽略。

Abstract: Aspects described herein relate to throttling packet-switched (PS) call establishment in wireless communications. A circuit-switched (CS) call can be conducted by using a first radio access technology (RAT). A cell update (CU) procedure for a PS call using a second RAT can be detected as due to one or more conditions. A cause for the one or more conditions can be determined based on one or more parameters related to a transmitter or receiver. PS call establishment attempts can accordingly be throttled based at least in part on determining the cause for the one or more conditions

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a user equipment (UE) or component thereof. The apparatus may be configured to transmit to a base station a first request to transmit data in a buffer. The apparatus may be further configured to transmit to the base station a second request to transmit the data in the buffer in absence of a grant in response to the first transmit request. The apparatus may be further configured to remain awake for at least a portion of a scheduled discontinuous reception (DRX) sleep state following the transmission of the second request.

Abstract: In wireless communication, uplink communication by a wireless communication system user equipment may include providing data packets by a data source in the user equipment, detecting a pattern relating to uplink transmission of the plurality of data packets, and scheduling transmission of the plurality of data packets by the user equipment. One or more aspects of scheduling transmission of the plurality of data packets may be based on the detected pattern.
